vwill enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this speciiication.

This invention relates to new and useful improvements in dust collectors and water traps, designed for use in connection with pressure pipes upon railway trains, pumps, etc., and the object in view is to produce an automatic mechanism whereby dust and water' may be separated from the line pipe or pump.

My invention comprises various details of construction and combinations and arrangements ot parts which will be hereinafter' fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

l illustrate my invention in the accompanying drawings, in which Figure l is a central vertical sectional view through a trap made in accordance with my invention. Fig. 2 is an end elevation of the shell of the casing, the parts being indicated in dotted lines. Fig. 3 is a sectional Fig. 4 is a sec tional view on line 4-4 of Fig. 1, and Fig. 5 is a detail View of the valve ring.

Reference now being had to the details of the drawings by letter, A designates the valve casing which, as shown i'n the views, is tapered, Haring upward, and is provided with an intake port B opening into the chamber C and an exhaust port D with an integral shell portion D' communicating between 'the same and the interior of the chambered part F which has a passageway E leading therefrom into the chamber C, the course of the air passing through the casing being designated by arrows. Said casing has a spreading partition, designated by letter H, which is tapered to alpoint at H', which latter extends into the opening through which the air enters, leaving a space upon either side, the tapering surface of said partition serving as a defiecting means for the air which enters the casing. Said partition or spreading web is made preferably integral with the wall of the casing and tapers at substantially an angle of G0 degrees to the point which extends any suitable distance within the inlet opening.

The lower portion of the casing has a chamber K aud on opening K', the wall of which isithreaded and adapted to receive the valve box N which has threaded connection therewith. Said valve box has a central longitudinal passageway O leading its entire length and is provided with inclined branching nassageways O leading through the circun Aerence of the box and a valve stem Q mounted to have a longitudinal movement within said passageway O, a sulicient space intervening between its circumference aud the wall of said passageway whereby the dust, water and other foreign matter may readily escape therethrough. A. head. des

.ignated by letter L. has a threaded hole for the reception of the upper threaded end of the stem Q, said head being'conical shape and extending into the lower part of the chamber C and designed to be acted upon oy the pressure or" the air passing through the casing. To guide said head in its vertical movements, pins M' project from the valve box and are guided through apertures in said head.

The top ot' the valve box is counterbored to receive a valve ring P. Said valve ring, which tits snugly within the counterbored recess in the top of the box, is provided with holes I (eight being shown in the drawings) of suitable dimensions and which extend partially through the ring and open through the inner marginal circumference of the latter, as shown in the drawings, and through which the air, water and foreign matter are adapted to pass. A coiled spring R, treated to resist a certain pressure, say ten pounds, to the square inch rests upon said packing ring outside of the holes P and also bears against the under surface of the head L.

A valve T is iitted to said stem and is counterbored to receive a suitable paclrin T' fit-.tened to the bottom oi the valve an which packing is provided with an annular groove T2 upon its under surface which is adapted to lit over a beading'T3 about the upper marginal edge of the passageway O when the valve is seated and the circumference of said valve is ground to make a perfcct working fit in the valve ring. A lever W is provided which is recessed at W and is pivotally mounted upon a pin `W2 carried by the recessed walls N of the valve box and is adapted to pass underneath the lower end of the stem and serves as a means whereby the valve may be operated by the tilting of the lever should it be desired to allow the foreign matter to escape to the atmosphere.

In operation, when the device is used in connection with,i fluid under pressure, the pressure of libe. air within the chamberedportion of the casing will be suiiicient to overcome the tension of the spring'R and hoid the valve seated and any water, dust or other foreign matter which may enter the casing may settle into the chamber K in readiness to be discharged when `the valve is open. ln the event of the pressure upon the'air in the casing being relieved in any way by its being cut off by the engineer of the locomotive connected to a train equipped with the apparatus, the tension of the spring would cause the valve to unseat and allow the water and foreign matter to escape through Ithe passageways O and G. The air from which the water, dust or foreign matter has been separated will take the course designated by the varrows to the casing. A

What I claim to be new is 1. A dust and water trap for fluid pressure lines, pumps, etc., comprising a casing provided with a defiecting partition dividing the casing into two compartments with a communicating opening between the same,

an inlet opening communicating with one compartment and an exit opening with the other, a valve box fitted within an opening in said casing and provided with an exit passageway, an apertured valve rlng seated vin said box, a valve mounted within said ring', a stem fixed to the valve, a head upon said stem, and a spring interposed between the ring and head, as set forth.

2. A dust and water trap for fluid pressure lines, pumps, etc., comprising a casing provided with a deflecting partition dividing the casing into two compartments with a communicating opening between the same, an inlet opening communicating with one compartment and an exit opening with the other, a valve box fitted within an opening in said casing and provided with an exit passageway, a ring seated in the upper and a counterbored recess in the top of said box and having passageways leading through the upper face thereof and the inner marginal edge of the ring, a valve mounted within said ring and adapted to regulate said passageways thereof, a stem passing th'roughy said exit` passageway of the valve bea and to which the valve is fastened, a

head fixed to the stem, and a spring interposed between the ring and head, as set forth,

3. A dust and water trap for fluid pressure lines, pumps, etc., comprising a casing provided with a detiecting partition dividing the casing into two compartments with a communicating opening between the same, an inlet opening communicating with one compartmentand an exit opening with the other, a valve box fitted within an opening in said casing and provided with an exit passageway, a ring seated in the' upper and a counterbored recess in the top of said box and having passageways leading through the upper face thereof and the inner marginal edge of the-ring, a valve mounted within said ring and adapted to regulate said passageways thereof, a stem passing through said exit passageway of the valve box and to which the valve is fastened, a conical-shaped head fastened to the upper end of said stem, and a spring interposed between the ring and head, as set forth.
